Why not keep your name in code itself (Score 1)

you dont have to show the end user that you were there, but having your name as a graffiti allover the program in comments will serve your purpose of recognition. However, if you want to add soem humour, I dont think it's a good idea in a professional program, after all this might come back at you when an auditor or quality controller looks into the software, it might harm your career.
